7.2
Step-by-step explanation:
16.76 = 16.8
9.611 = 9.6
16.8 - 9.6 = 7.2
Answer:
Area = x^2+4x+3
Step-by-step explanation:
The volume of a box is given by the expression
x^3 + 3x^2 - x-3. The height of the box is given by the expression x-1.
volume of the box = Length * width * height
L is the side length of the box;
Given
V(x) = x^3 + 3x^2 - x-3
Factorize
V(x) = x^2(x+3)-1(x+3)
V(x) = (x^2-1)(x+3)
V(x) = (x+1)(x-1)(x+3)
V = LWH
V = Area * Width
Since the height of the box is x - 1
Area = (x+1)(x+3)
Expand
Area = x^2+3x+x+3
Area = x^2+4x+3
Answer:
D
Step-by-step explanation:
as x increases by 1, y increases by 35
Answer:
33.
Step-by-step explanation:
( 25 + 29 + x) = 3*29 = 87
x = 87 - 25 - 29
x = 87 - 54 = 33.
